What is a workspace?

In Structurizr, a workspace is the wrapper for your software architecture model, views and supplementary documentation. Workspaces can be created using one of the Structurizr client libraries or the browser-based workspace editor. We recommend that a workspace contains the model, views and documentation for a single software system.

Free plan

The free plan allows you to create diagrams and documentation, but it excludes team-based features such as role-based access, sharing links, workspace versioning, full-text search, embedding diagrams from workspaces (e.g. iframe and Atlassian Confluence), and Slack integration.

Paid plans

The paid plans are aimed at teams and provide access to the full feature set, with a varying number of workspaces. Plans with more than 25 workspaces are available for yearly purchase; please contact us for pricing.

Cloud plans

Our cloud plans allow you to get started with Structurizr quickly, without needing to host and update software on your own servers. You can read about how and where data is stored, and our privacy policy explains how we use your data.

Per team pricing, not per user

Unlike typical software modelling and documentation tools, where the pricing is hundreds or thousands of dollars "per user", Structurizr's pricing is designed to be "per team", for whatever your own definition of a "team" is.

"Per user" licensing tends to result in a common anti-pattern where a small number of people end up being responsible for updating diagrams, with the resulting diagrams often being manually exported to static images for inclusion in documentation or wiki pages. We think that good software architecture diagrams and documentation should be accessible by everybody on the team, rather than just those lucky few individuals who are fortunate enough to have licenses for tooling.

Workspaces owned by a paid customer can be shared with free users, so you only need to purchase one subscription for your team.

The "Team Plan" is now known as the "Cloud Plan". The "Personal", "Standard" and "Enterprise" plans have been discontinued and are no longer available for purchase. Existing active subscriptions are unaffected.

On-premises installation

We also have a standalone version of Structurizr that can be run locally on your own server, providing the majority of the same features found in the cloud service. A subscription grants you a perpetual license to use the software on your own server, although software updates will only be available for the duration of a valid subscription. See On-premises installation for more details.

Frequently asked questions

Is there a free plan and trial?

Yes, the Free Plan is aimed at individuals, and provides a single workspace with the basic features needed to create software architecture diagrams and documentation. After signing up for our Free Plan, if desired, you can activate a free 14 day trial by using the link on your dashboard. This trial allows you to create up to 3 workspaces and unlocks all of the available features. This is obligation free and no payment details are required. After the trial period, your account will revert back to the Free Plan.

Do you manage credit card details yourself?

No, we use Braintree Payments (a PayPal company).

Which credit cards do you accept?

We accept Visa, Mastercard and American Express.

Refunds

All payments are strictly non-refundable. Please contact us for an extended trial if necessary before starting your subscription.

Cancelling a subscription

To cancel a subscription, and prevent it being renewed, use the link on your dashboard.

Changing a monthly subscription

There is currently no way to change an active subscription. If you'd like to move to a larger cloud plan, you will need to cancel your current subscription using the link on your dashboard to stop the recurring payment (this does not affect your existing workspaces), and re-subscribe when your current month expires. If you'd like immediate access to the larger plan, please raise a support ticket via your dashboard, after you've cancelled your current subscription.

Updating credit card details

We do not have access to your credit card details, so it is not possible to change these to reflect a new credit card number or revised expiry date. To change your credit card details, please cancel your current subscription using the link on your dashboard, and follow the instructions in the confirmation e-mail about how to resubscribe to the same plan.

Failed payments

If a subscription payment fails for any reason, your subscription will be cancelled. In this situation, we will send you an e-mail with instructions about how to resubscribe to the same plan with alternative payment details.

EU tax for b2c transactions

Individuals in the EU are subject to tax at their local rate for the supply of digital services via the Internet (see Electronically supplied services for more details). EU registered businesses can enter their EU VAT number during the purchase process to have VAT deducted.

Purchase orders, invoicing and wire transfers

We're a small company, and due to the large overhead typically involved (supplier registration, vendor questionnaires, chasing late payment, etc) purchases for yearly subscriptions made via a purchase order/invoice and wire transfer will incur an additional $100 administration fee. Please contact help@structurizr.com with your business name, address and any purchase order details. Due to the EU VAT place of supply rules, EU registered businesses must also include their EU tax number to avoid being charged VAT at the local rate.

Resellers

Due to the additional overhead associated with indirect sales, a $100 administration fee will be added for all sales through resellers. No reseller discounts are available.

What happens to my workspaces when my paid plan expires?

Users on the Free Plan can create one workspaces so, when your paid plan expires, the workspace that you created first will be retained as-is. The other, more recent, workspaces will be retained too, but marked as read-only. You can still view the workspace content (via the UI and web API) but no changes can be made.

Do you support open source projects, academic establishments, and non-profit organisations?

Yes, free cloud-based plans are available for open source projects, academic establishments, and public speakers and trainers. Discounts are available for other non-profit organisations.
